Rail sizing and rack compatibility matrix

For specific information about the rail solutions compatible with your system, see the Dell Enterprise Systems Rail
Sizing and Rack Compatibility Matrix available at
Docs_Documents/en/rail-rack-matrix.pdf.
The document provides the information that is listed below:
● Specific details about rail types and their functionalities.
● Rail adjustability range for various types of rack mounting flanges.
● Rail depth with and without cable management accessories.
● Types of racks supported for various types of rack mounting flanges.
B29 sliding rails for 4-post and 2-post racks
● Support stab-in installation of the chassis to the rails.
● Support for tooled and tool-less installation in 19" EIA-310-E compliant square, unthreaded round hole and threaded round
hole 4-post racks.
● Support for tolled installation in 2-post rack.
● Support full extension of the system out of the rack to allow serviceability of key internal components.
● Support for optional strain relief bar (SRB).
● Support for optional strain cable management arm (CMA).
NOTE: The CMA is less useful if the rack is mixed with short depth server and long depth server
For situation where CMA support is not required, the outer CMA mounting brackets can be uninstalled from the sliding rails. This
reduces the overall length of the rails and eliminates the potential interferences with rear mounted PDUs or the rear rack door
B30 sliding rails for Pelican custom racks
● Support stab-in installation of the chassis to the rails.
● Support for tooled installation in Pelican custom racks.
● Support full extension of the system our of the rack to allow serviceability of key internal components. Support for optional
